Welcome to the Optima Forums.
I think most of us here on the forum that have been around for awhile are aware of it.
As mentioned above, they did not offer the LX Turbo until the 1.6T model was released in 2016.
For the 2011 & 2012 Kia Optima Models, there was only 2 options to choose from for engine types. (Other than the Hybrid engine)
There was a 2.0T offered in the EX & SX trim levels, and of course there was the 2.4L engine offered in the LX & EX trim levels as well.
In 2013, the SX-L was introduced to the market, and the EX was not offered as a turbo model any longer, making the 2013 turbo only offered in the SX & SX-L trims.
What kind of information were you looking for on that year and model of Optima?
